I considered trying the guillotines but I did not want to completely retool my bow. Also, there isn't really a good way to practice with those things, and no amount of convinceing will have me buy in to them flying like a field point...

I went with Rocket Hammerheads. 2" cutting diameter. With that older Bear that isn't throwing an arrow quite as fast as my Hoyt, I would shoot a 2 - 4 blade fixed broadhead.
